Starbucks is offering a birthday cake-flavored Frappuccino in honor of the 20th birthday of its signature frozen drink.

Don't start salivating just yet. The limited-edition beverage will only be available for five days, starting tomorrow, March 26, and ending on March 30.

So, what's in a birthday cake frap?

The coffee giant will blend its vanilla bean and hazelnut flavors together to create the perfect taste.

Not only is the drink guaranteed to be delicious, but it is visually appealing as well. The frap will be topped with a raspberry-infused (pink) whipped cream, according to People.

Frappuccinos have come a long way since 1995, and are now one of Starbucks' most popular menu selections. They were originally made in mocha and coffee flavors, but the company has experimented with fun, colorful options, too.

Starbucks has made a blue Seattle Seahawks flavor, a bright green Franken Frap for Halloween and a frozen version of Chestnut Praline, People reported.

If you've ever had one of Starbucks' cake pops, this ought to be good. Hurry and get it while it lasts.

You never know, the drink could always come back in French Toast Crunch-like fashion.
